## Overview

In the Linux kernel, the following vulnerability has been resolved:

drm/msm: Fix task_struct reference leak in recover_worker

get_pid_task() increments the task reference count, but the
corresponding put_task_struct() was missing in the else branch,
leaking a reference on every GPU hang recovery.
